Specification of Letters Patent.

Patented April 16, 1907.

Application filed August 28, 1906, Serial No. 332,333.

To all whom it may concern."

Be -it known that I, SHERMAN W. STEWART, a citizen of the United States,and a resident of Spencer, in the county of Owen and State of Indiana,have invented a new and Improved Cream-Separator, of which the folelowing is a full, clear, and exact description.

This invention is a novel device forseparating the cream that rises-tthe upper sur- I I0 face of milk, and is especially designed for drawingoff the cream that collects at the top of milk-bottles as delivered forfamily use, thus adapting it for a household convenience and as adesirable kitchen article. One embodlment of the lnventio-n consists ofa cap constructed-to form an alr-tlght coni nection with the mouth of abottleand having an air-compressor and a tube in connectron therewith,the compressor acting to force the cream through thetube to anyconvenient receptacle for receiving it.

A di aphragm is carried at the lower end of the tube, acting to preventthe milk from entering it and also forcing the drawing of the cream fromthe sides of the bottle.

Reference is t,0, be had to the accompanying drawing, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts, and in which the figure of. the drawing representsthe upper portion of 'a milk-bottle with my improved device applied tothe mouth thereof, the compressor of the device being shown partly invertical central section.

The invention comprises a cap lof-sufficient size to cover the mouth ofan ordinary milk-bottle and has a covering 2, ofsheet rubber, on itsunder face, thus adapting the joint between the cap and themouth of thebottle to be madeair tight by a slight pressure with the'hand. Passingthrough the cap 1 is a tube 3, having a curved overhanging outer end 4for discharging the milk into v side of the bottle. The. tube 3 projectsinto 7 the bottle to near the line separating the suitable receptacleheld or seated at one cream from theymilk, as represented in dotted linein the drawing fi ure.

/ .Attach d to the lower end of thetube 3 is a diaphragm 5, slightlyseparated from the month of the tube and in concentric relation Itherewith. ;The diaphragm is preferably twosubscribing witnesses.

supported above the tube by a sleeve 6, having a downwardly-inclined arm7, connecting the diaphragm 5 at its outer edge; The sleeve 6, ifdesired, can be made to 'slidably fit and frictionally embrace the tube3, en-

abling the distance between the diaphragm 5 and the mouth of the tube tobe adjusted,

Attached to the upper end, of the cap 1 is a small air-compressorcomposed of a cylinder 8 and a piston 9, adapted to be reciprocatedtherein. The piston is operated by a stem 10, passing through the uppercylinder-head,

acting to force the air by a valve 11, opening downwardly and into thebottle.

In the use ofthe device it is placed on the.

bottle as illustrated in the drawing figure and a slight pressurebrought to bear on the cap by the hand, acting to make a tight jointbetween the cap and the bottle-mouth. The stem 10 is then reciprocatedto compress the air and force it into the bottle, thus causing the creamto rise inthe tube 3 and be discharged from its curved end to anysuitable receptacle for receiving it.

means, a diaphragm carried at the lower end of the tube, and means forforcing air into the bottle. I

2. In a cream-separator, a cap having a rubber covering on its'underface, a tube passing through the cap; having an outer curved. end, adiaphragm carried at the lower end of the tube, and an air-compressorcarried by the cap.
